Bandwidth allocation device for guaranteeing QoS in ethernet passive optical access network |
摘要 |
An apparatus and method for allocating a bandwidth for up-stream data transmission to a plurality of Optical Network Units (ONUs) in an Ethernet Passive Optical Access Network (EPON) in which the ONUs are connected to a single Optical Line Terminal (OLT) are disclosed. The bandwidth allocation method for guaranteeing a Quality of Service (QoS) in the EPON includes the steps of: a) classifying up-stream data to be transmitted from a plurality of Optical Network Units (ONUs) of the EPON to an Optical Line Terminal (OLT) into a plurality of classes according to predetermined data priority information, and requesting bandwidths required for individual classes from the OLT; b) allowing the OLT to perform a bandwidth distribution process according to bandwidth requirement quantities of individual classes using weights pre-assigned to individual classes; and c) allowing the OLT to distribute a residual bandwidth acquired after the bandwidth distribution process is performed from among an available total up-stream bandwidth to the ONUs.
